Subject: [Bug 1803838] [NEW] Mailman Upgrade to 2.1.29 - Ubuntu 16.04
Message-ID: <154249494734.26726.3840053317022915105.malonedeb@soybean.canonical.com>

Public bug reported:

In Ubuntu 16.04 LTS the version of Mailman currently available in the
package manager is 2.1.20 while the latest one is 2.1.29 and which is
also the latest available on Mailman website.

There has been several bug and security fixes since 2.1.20 to 2.1.29
which look interesting to get the package managed upgraded.

What it takes to get the package bumped to 2.1.29 in Ubuntu 16.04 ?

Public bug reported:

Hi,

We have updated our external MTA to use OpenBSD(6.4) and opensmptd.

After we updated, mailman started to send "bounce message w/no
discernable addresses" messages to us (list admins). It seems that
mailman is not able to parse bounce messages sent from opensmtpd.

Please check an example of a bounce message from opensmtpd:

    Hi!

    This is the MAILER-DAEMON, please DO NOT REPLY to this email.

    An error has occurred while attempting to deliver a message for
    the following list of recipients:

XXXXXXXXX at live.com: 550 5.5.0 Requested action not taken: mailbox
unavailable. [VE1EUR02FT047.eop-EUR02.prod.protection.outlook.com]

    Below is a copy of the original message:

We are using mailman 2.1.11 and I could not test the issue on version
2.1.17. But, reading the code, it seem that the problem is still there.

We managed to fix the problem by editing the file
'mailman/Mailman/Bouncers/SimpleMatch.py' and including the following
lines:

191,194d190
<     # opensmtpd
<     (_c('An error has occurred while attempting to deliver a message for'),
<      _c('Below is a copy of the original message'),
<      _c('^\s*(?P<addr>[^\s@]+@[^\s@]+)')),

patch follows attached

Regards,

Cristiano

Thank you for the report and suggested patch.  If possible, please post
the entire, raw bounce message including all headers. We need that for
the testing data. Also, depending on the headers and MIME structure of
the message, SimpleMatch may not be the optimum recognizer.

Hi Mark,

Thanks for your answer.

I'm attaching one of the messages that mailman have sent to us. But I
had to anonymize some headers. Hope it is still useful for you guys.

In my last message, I said that we was using version 2.1.11. This info
was wrong: we are in 2.1.17. The patch that I have sent applies to this
version (not 2.1.29 nor 2.1.11).

Thanks,

Thanks for the message. The anonymizing is not a problem. It turns out
that this is almost an RFC 3464 compliant DSN and should be recognized
by Mailman/Bouncers/DSN.py except for the fact that the 'action' in the
Delivery Report is 'error'. This is non-compliant. RFC 3464, sec 2.3.3
defines action as:

      action-value =
            "failed" / "delayed" / "delivered" / "relayed" / "expanded"

Thus, 'Action: error' in this DSN is non-compliant. It should be
'Action: failed'. You may wish to report this to the opensmtpd
developers.

If the mean time, if you look at Mailman/Bouncers/DSN.py at line 59,
you'll see

            if not action.startswith('fail'):
                # Some non-permanent failure, so ignore this block
                continue

If you change that to

            if not (action.startswith('fail') or action.startswith('error')):
                # Some non-permanent failure, so ignore this block
                continue

this DSN should be recognized by DSN.py. I'll be incorporating this fix
for the next release.
